Former US president Donald Trump’s historic second impeachment trial will force the Senate to decide whether to convict him of incitement of insurrection after a violent mob of his supporters laid siege to the US Capitol on January 6.
While Mr Trump’s acquittal is expected, Democrats hope to gain at least some Senate Republican votes by linking his actions to a vivid description of the violence, which resulted in five deaths and sent legislators fleeing for safety.
Mr Trump’s lawyers say the trial should not be held at all because the former president is now a private citizen. They argue that he did not incite the violence when he told his supporters to “fight like hell” to overturn his defeat.
Here is a look at the basics of the impeachment trial:
– How does the trial work?
As laid out by the constitution, the House votes to impeach and the Senate then holds a trial on the charge or charges. Two thirds of senators present can convict.
The chief justice of the United States normally presides over the trial of a president, but because Mr Trump has left office, the presiding officer will be Democratic Vermont Senator Patrick Leahy, who is the ceremonial head of the Senate as the longest-serving member of the majority party.
Once the senators reach a final vote on the impeachment charge – this time there is just one, incitement of insurrection – each legislator will stand up and cast their vote: guilty or not guilty.
– How long will the trial last?
It is likely to be more than a week. The agreement between Senate leaders provides for up to 16 hours for both prosecutors and the defence to make their arguments, starting on Wednesday, with no more than eight hours of arguments per day. Later, there will be time for senators to ask questions, and there could be additional procedural votes.
Mr Trump’s lawyers are likely to begin their arguments on Friday and finish on Saturday. That almost certainly means a final vote on Mr Trump’s conviction will not happen until next week.
Mr Trump’s first impeachment trial, in which he was acquitted on charges that he abused power by pressuring Ukraine to investigate now-president Joe Biden, lasted almost three weeks. But this one is expected to be shorter, as the case is less complicated and the senators know many of the details already, having been in the Capitol during the insurrection.
And while the Democrats want to ensure they have enough time to make their case, they do not want to tie up the Senate for long. The Senate cannot confirm Mr Biden’s cabinet nominees and move forward with their legislative priorities, such as Covid-19 relief, until the trial is complete.
– Will there be witnesses?
It appears unlikely, for now, though that could change as the trial proceeds. Mr Trump himself has declined a request from the impeachment managers to give evidence.
If the managers do decide they want to call witnesses, the bipartisan agreement for the trial allows them to ask for a vote. The Senate would have to approve subpoenaing any witnesses for the trial.
– Why try Trump when he is out of office?
Republicans and Mr Trump’s lawyers argue that the trial is unnecessary, and even unconstitutional, because Mr Trump is no longer president and cannot be removed from office. Democrats disagree, pointing to opinions of many legal scholars and the impeachment of a former secretary of war, William Belknap, who resigned in 1876 just hours before he was impeached over a kickback scheme.
If Mr Trump were convicted, the Senate would take a second vote to bar him from holding office again, Senate Majority Leader Chuck Schumer said on Monday. Democrats feel that would be an appropriate punishment.
In response to Republican efforts to dismiss the trial, Democrats argue that there should not be a “January exception” for presidents who commit impeachable offences just before they leave office. They say the trial is necessary not only to hold Mr Trump properly accountable but also so they can deal with what happened and move forward.
“You cannot go forward until you have justice,” said House Speaker Nancy Pelosi last week. “If we were not to follow up with this, we might as well remove any penalty from the constitution of impeachment.”
– How is this trial different from Trump’s first trial?
Mr Trump’s first trial was based on evidence uncovered over several months by the House about a private phone call between Mr Trump and the president of Ukraine, as well as closed-door meetings that happened before and afterwards. Democrats held a lengthy investigation and then compiled a report of their findings.
The fresh memories of January 6 could make it easier for the House impeachment managers to make their case, but it does not mean the outcome will be any different. Mr Trump was acquitted in his first trial a year ago on Friday with only one Republican, Utah Senator Mitt Romney, voting to convict, and there may not be many more guilty votes this time around.
In a test vote on January 26, only five Senate Republicans voted against an effort to dismiss the trial – an early indication that Mr Trump is likely to be acquitted again.
– What will Trump’s lawyers argue?
In a brief filed on Monday, they argued that the trial is unconstitutional, that Mr Trump did nothing wrong and that he did not incite the insurrection during his January 6 speech to supporters.
The brief goes after the impeachment managers personally, claiming that the Democrats have “Trump derangement syndrome”, are “selfish” and are only trying to impeach Mr Trump for political gain.
There was no widespread fraud in the election, as Mr Trump claimed falsely over several months and again to his supporters just before the insurrection. Election officials across the country, and even former attorney general William Barr, contradicted his claims, and dozens of legal challenges to the election put forth by Mr Trump and his allies were dismissed.
– What would acquittal mean for Trump?
A second impeachment acquittal by the Senate would be a victory for Mr Trump – and would prove he retains considerable sway over his party, despite his efforts to subvert democracy and widespread condemnation from his Republican colleagues after January 6.
While they have not said yet if they will push for a censure vote after the impeachment trial, Mr Kaine said last week that “the idea is out there on the table and it may become a useful idea down the road”.
